Specification of Letters Patent.

Patented Feb. 27, 1906.

Application filed June 6, 1905. Serial No. 283,974.

To all whom if may concern Be it known that I, MARION ADDY, a citi zenof the United States, residing at Peoria, in the county of Peoria andState of Illinois, have invented certain new and useful Improvements inEqualizers; and I do hereby declare that the following is a full, clear,and exact description of the invention, which will enable others skilledin the art to which it appertains to make and use the same.

This invention has reference to new and useful improvements in means forequalizing the draft of that character wherein bellcrank levers areutilized to which doubletrees are connected and the said bell-cranklevers connected to an evener, the object being to construct afour-horse equalizer in which three horses are hitched to walk abreaston one side of the tongue and a single animal on the other side.

The device is particularly applicable to harvesters or binders to ermitthe single animal to travel on the sic e next the standing grain.However, the device may be used wherever similar circumstances orrestriction of space occurs.

The invention relates more particularly to a tongue, a bar supported bythe tongue, bellcrank levers pivotally attached to p osite ends of thebar, a reach or arm pivotai y at tached to the tongue, an evenerpivotally connected to the free end of the reach rods connected to thebell-cranks supported by the bar and their opposite ends connected withopposite ends of the evener, and a bell-crank lever pivotally attachedto the tongue in the elbow of the said lever, having one end con nectedwith the pivot of the evener and to the opposite end attached to a rodwhich at its opposite end is connected to the framework of a harvesteror other machine.

This application is filed asa substitute for the application filed by meon the 30th day of November, 1904, hearing Serial No. 234,889, whichcontains substantially all of the features shown in the presentapplication with the exception of the connections between the evener andthe harvester or other mechine.

That my invention may be more fully understood reference is had to theaccompanyin drawings, in which igure 1 illustrates in plan m improveddraftequalizer, and Fig. 2 is a si e elevation in detail of partsattached to the tongue of the equalizer.

Reference being had to the drawings, 1 denotes the tongue or pole, whichmay be of the usual and approved construction. On the tongue is attachedthe bar or rest 2, which has portions 3 and 4 extendin u on oppositesides of the said tongue. he ar or rest 2 may be of any suitable lengthand braced to the tongue in any convenient and desirable manner.

To the portion 3 of the bar 2 and at or near the outer end thereof isivoted at 5 the bellcrank lever 6, formed 0? the right-angle extensions7 and 8, the former lying normally above and arallel with the bar 2 andthe free end thereo ositioned above the center of the tongue, t eortions 7 and 8. of the lever 6 connected by t e brace bar or web 9.

To the free end of the portion 7 of the lever 6 is coupled a doubletree10, the ends thereof extending upon opposite sides of the tongue, and tothe ends of the doubletree are connected the usual swin letrees 11.

12 designates a bel -crank lever, in all res ects similar to thatindicated as 6, the same pivoted at 13 to the portion 4 of the bar 2,and at or near the outer end thereof the same has the right-an leextensions 14 and 15, the former exten ing from and lying normally inthe same longitudinal direction of the bar 2, the extensions 14 and 15connected by the brace bar or web 16. To thefree end of the extension 14of the lever 12 is coupled a doubletree 17, and to the ends of thedoubletree are connected the usual swingletrees 18.

Connecting the bell-cranks 6 and 15 is an intermediate mechanism whichalso has connection with a frame of a harvester or other machine for thepurpose of equalizing the draft between the bell-crank levers and toplace the pull upon the side of the machine where the greatest draft iscreated. This mechanism consists of a reach 19, pivoted at to the tongueat the rear of the bar 2, be ing bowed u wardly and forwardly at 21 toat apt the p acing and o eration of certain arts. These parts are aell-cranlr lever 22, orrned of the ri ht-angle extensions 23 and 24, thesaid cran being ivoted at 25 to the ton e, and the end of t e extension23 pivota y attached at- 26 to the free end of the reach 19. Alsopivotally attached to the crank 22 and the end of the reach 19, wherethese two are pivotally attached, is an oscillating arm or evener 27, tothe rear end of which is attached a rod 28, which at its opposite end isattached to the end of the extension 8 of the lever 6, and 29 denotes arod similar to that indicated as 28, which connects the inner free endof the extension 15 of the crank 12 with the forward end of the arm orevener 27, and 30 denotes a rod, connected at its forward end to thefree end of the extension 24 of the crank and at its opposite end isattached at a suitable point to a frame part 31. This frame part(designated as 31) may be the forward frame or brace of a harvester towhich the tongue is attached or some other machine to which it isadapted to attach an equalizer. The tongue is braced by a bar or reach32 in the manner seen in the figure.

The function and 0 eration of the device are readily apparent rem thedrawings, together with the description of the same, and, while thedrawings illustrate the preferred form in which I wish to embody thedevice,

- it is obvious that various changes may be made in the detailconstruction and arrangement, and I do not wish to be confined to thedetails thereof.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent of the United States, is-

1. In an equalizer, the combination with the tongue, of a bar supportedby the tongue and having portions extending upon opposite sides thereof,a bell-crank lever pivotally attached to one end of the bar with itsinner end extending toward the center of the said bar, a secondbell-crank lever pivoted to the opposite end of the said bar with anextension of the lever extending some distance beyond the end of thebar, doubletree connections with the said levers, an evener pivoted tothe tongue at a point removed to the rear of the said bar havingoppositely-extended portions disposed longitudinally of the said tongue,and connecting-rods between the extensions of the evener and theopposite levers.

2. In an equalizer, the combination with a ton us, a bar supported byand transversely of t 1e tongue, levers pivoted to the opposite ends of.the bar, doubletrees attached to the said levers, a bell-crank leverpivoted to the tongue, an evener pivoted to the bell-crank, rodsconnecting the evener and the levers on the bar, and connections betweenthe said bell-crank and a frame part of a suitable machine.

3. In an equalizer, the combination with a ton ue, a bar supported byand transversely of tie tongue, levers pivoted to the opposite ends ofthe bar, doubletrees attached to the said levers, a bell-crank leverpivoted to the tongue, a reach also pivoted to the tongue,
